Examples of net.sf.saxon.event.Receiver

net.sf.saxon.event.Receiver
Receiver: This interface represents a recipient of XML tree-walking (push) events. It is based on SAX2's ContentHandler, but adapted to handle additional events, and to use Saxon's name pool. Namespaces and Attributes are handled by separate events following the startElement event. Schema types can be defined for elements and attributes.
The Receiver interface is an important internal interface within Saxon, and provides a powerful mechanism for integrating Saxon with other applications. It has been designed with extensibility and stability in mind. However, it should be considered as an interface designed primarily for internal use, and not as a completely stable part of the public Saxon API.
